ROAD DRAG.

Application led Aug'ust 25,1921. Serial No. 495,152.

To @ZZ whom t may concern.'

Be it known that I, HANSH. GosoH, a citizen of the United States, residing at Randall, in the county of Morrison and Statey of Minnesota, have invented certain new and useful Improvements in` Road Drags; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a road drag or scraper.

One important object is to generally improve the construction of a machine of this type and particularly that set forth in Let ters Patent of the United States #1,373,236 granted tome on March 25th, 1921.

Among the salient objects may be mentioned the provision of such a machine havf ing a novellifting or elevating mechanism for the drag or surface-engaging means; one in which the Scrapers and drag bar` may have vertical yielding movement upon encountering an obstruction; one having means to prevent undue lateral movement of the drag means and one having novel adjustable and reversible scraper blades.

Additional objects and advantages will become apparent from the description hereinafter following taken in connection with accompanying drawings of one practical embodiment.

ln said drawings Figure 1 is a side elevation of the improved machine;

Figure 2 is a plan view thereof;

Figure 3 is a plan view of the drag means detached from the machine;

Figure 4 is a cross-section on line 4-4 of Figure 2;

Figure 5 is a cross-section on line 5 5 of Figure 2, and

Figure 6 is a detail cross-section online 6-6 of Figure 2.

Throughout the different views like characters of reference designate like or corresponding parts. A. conventional wheeled structure of the type usually drawn by two or four horses, illustrates the application of the invention and may have a frame A provided with parallel side beams or bars 10. Rear wheels 11 are mounted on an axle 12 suitably journaled on the frame. Front wheels 13 are journaled on an axle 14 car- .ried by a draft or bitching structure 15 swiveled for lateral movement on a ball 16 on frame A by means of a socket 17. This ball and socket connection enables vertical tilting of the front wheels relatively to frame A when encountering an obstruction. The drivers seat is shown at 18. Foot rests may be provided on beams 10 at 18a.

Below and parallel with side beams 10 and the road are lifting bars 19 from which drag meansare suspended which in this instance comprise a drag bar or scraper blade B and a drag or plow scraper structure C. A flexible element 20 such as a chain is fastened at opposite ends as by rings 21 to each bar 19. Intermediate its ends, each chain is secured to a lever 22 pivoted at 23 to the adjacent side beam 10, and having a plunger mechanism 24 cooperating with a quadrant 25 on such beam to lock the lever in adjusted position. A pulley 26 is journaled on a stub shaft 27 on each beam 10 in the rear of the adja cent lever 22 while pulleys 28 and 29 are mounted on a stub shaft 30 projecting from e'ach beam. Guard plates are secured to beams 10 over the different sprocket chains employed. A supplemental guard plate is fastened to each guard plate 31, and extends` across pulley 29. Said chains 20, starting at their front ends, from lifting bars 19 pass over pulleys 29, are then connected to levers 22, then pass over pulleys 28 and 26 and are then fastened at' their rear ends to the lifting bars. As a result of this construction, levers 22 may be swung by the driver while seated to cause the chains 20 to raise and lower the lifting bars and the drag means supported thereby in a plane al ways horizontal and thus parallel with the road and with said beams 10. Chains 2O may also pass over suitably positioned idler pulleys 20L to avoid interference with levers 22.

Suspended from the lifting bars 19 as by means of chains or flexible elements 32 are supporting bars 33 connected by horizontal pivots 34 to supporting bars 35 suspended by flexible elements or chains 36 from bars 19. Scraper blade B is elongated and angularlv disposed, having'a reinforcing rib 37. Brackets 38 depend from bars 33 and are secured to said rib 37 to support said blade B. Struts 39 connect and brace said bars 33.

Structure C has a main beam 40 rigidly secured to said supporting bars 35. Paralpend below theholders 45. ln due course the blades wear even with the holders at which time they may be reversed to present the other sharpened edge for use.

Beam 4l is adapted for movement longitudinally relatively to and toward beam 40 to swing the holders 45 and blades 48 to different angles, such movement being permissible due to the provision of said slots 43 and pins 44. To this end, a lever is pivoted on beam 41 at 5l and swings relatively to a segment or other means 52 to which it may be fastened in adjusted positions. Pivoted to said lever 50 at 53 is a'link or draw member 54 pivoted at 55 to the beam 40.

Secured as to the front of frame A are draft chains 56 which are fastened to supporting bars 35 and which may be upheld so as not t0 interfere with operation of the front wheels and adjacent parts by means of a chain 57 spanning side beams l0.

ln order that the drag means may not unduly move laterally relatively to the frame A, one of the lifting bars 19 is disposed in openings 58 of brackets 59 supported bv rods 60 which swing vertically in bearings 6l on beams l0. Struts 62a reinA force the brackets. Chains 62 and 63 eX- tend from the brackets 59 to the beams 40 and 4l most remote therefrom, respectively.

It will be realized that the height of the drag means is controlled by the adjustment of levers 22 which through the medium of chains 20 raise and lower the same, always maintaining same parallel with the ground.

i be resorted to.

'Vhat is claimed is l. A machine of the class describedhava lifting bar, a supporting beam flexibly suspended from the bar, a second supporting beam flexibly suspended from the bar, means permitting relative movement of said bars on a horizontal axis transverse to the machine, and independent drag means supported from said bars. p

2. f'i machine of the class described having pivoted brackets, a lifting bar mounted in said brackets, means to raise and lower said lifting bar, supporting members pivoted together and suspended from the lifting bar, chains extending from said brackets to the remote supporting members, and drag' means carried by said supporting members.

A. road scraper having a beam, a second beam, said beams being spaced apart, blades pivoted to said beams, a lever pivoted to one of said beams, a link means pivoted to said lever and to the other of said beams, one of said beams being provided with an- `gularly disposed slots, supporting` members rigid with the other beam and projections on saidv supporting members entering said slots.

in testimony whereof I affix my Vsignature in presence of two witnesses.
